Flatbillers, AKA Bros - You've seen them. Those tattooed kids who drive lifted trucks, wear flat-billed hats turned to the side and constantly talk about dirt bikes. These tough guys affectionately refer to each other as "Bro". Are they for real? Or are they just posers? Flatbiller.com dives headfirst into the underground world of the Flatbiller to find out.

The Onion, a weekly parody newspaper, just printed their take on bros. Here's a little bit of it.

You know you're one of my top bros, bro, because you got my back. And I got yours. You're my bro. But you went above and beyond the other night, bromaldehyde. You really did. Saving me that seat at the Velvet Revolver show, even though all those other bros were trying to get up front, bro? So clutch.

After a long career marked with several failures and image makeovers, Vanilla Ice, aka Robert Van Winkle, has latched on to the Bro Movement.

Like Vanilla Ice, I too, have failed you. I should have seen this one coming. All of the signs were there - white boy rapper, tattoo'd action sports fan, strong desire to follow the latest trend. Vanilla Ice is another trophy on the shelf of the Bro Nation.

For a long time, there was a great article on Wikipedia that defined Bros and Flatbillers. Unfortunately the article was deemed "Original research", and the Wikipedia admins deleted it a few months ago.

I managed to save the article and I moved it over to Dirtopia, where it can exist forever. I think the article could use some work, so feel free to head over to Flatbiller on Dirtopia and improve it. Just click "edit this page".

The Kottonmouth Kings (aka KMK) have been at the forefront of the Flatbiller craze from the very beginning. These pioneers of white-boy rap are walking billboards for their own certified Bro Brand "SRH Clothing".

As far as we can tell, most KMK music is centered around getting high and drinking beer.

KMK love is almost universal among flatbillers. We have yet to come across a bro who doesn't like them.

As a cultural refugee originally from Riverside-the eye of the brohurricane-I know a thing or two about the dreaded Flatbillers. My friend Brian here (who I knew when he was just my friends gawky little brother, the one day, voila, Uber-Bro) takes it to the X-Treeme in just about every facet of his life. I don't really know what else to say that his profile doesn't say better. On it you'll find a little bit of everything to make your meth-addled trucker-hat wearing heart glow.

Marvel at his gnarlator tattoos. Turn green with envy at his air-bag enabled '63. Laugh your ass off at the almost endless supply of Bro-pary pics that come complete with wigger gang signs and uplifted middle digits.

Anyone who lives in SoCal knows that local radio station KROQ's producer "Lightning" loves the big bro trucks. Brandon, one of our loyal fans, sent us this photo of Lightning standing under what is possibly the largest bro-truck on earth.

When asked about the truck, Lightning claimed that the truck was not his. "I borrowed the truck from a guy in the 909. I was a joke. I drove it in a parade." Sure buddy.

Lightning reassured us that he makes fun of flatbillers all the time. Unfortunately for him, our research uncovered additional ties to the "Long Beach Clothing Company" that is so boldly stamped on the side of his favorite truck. Even worse, we discovered that this store was also a major distributor of certified bro brands such as Famous and West Coast Choppers.

The only piece of evidence that Lightning has in his defense: he appears to be wearing a Santa Claus hat.

Every exploding trend leads to some sort of backlash, and flatbillers are not exempt.

Take, for instance, Ryan and his friends. They threw what he calls "a bro/bro hoe theme party".These brave souls got fully decked out in all of their flatbiller gear and simulated the bro lifestyle for a few hours. They even got together for the "token bro shot", attending to every last detail, all the way down to one bro giving the finger.Bandanas, flatbills, neck tattoos, white boy finger poses. I don't think they missed anything. There are a few more pics on Ryan's MySpace. Stop by and say hello.
